    Abstract: Methods and apparatus for resolving incomplete message content in networks. Various embodiments of the present disclosure are directed to correction and recovery of incomplete measurement report configuration messages within a Long Term Evolution (LTE) network. Specifically, within certain LTE networks, existing messaging may be incomplete in regards to various nearby ancillary networks, but still sufficient with regards to measurement requirements of the LTE network itself. Since the mobile device can continue operation within the LTE network, the mobile device can safely ignore or correct the measurement report configuration message.

    Abstract: Methods and apparatus for power optimization in e.g., a wireless mobile device. In one embodiment, the optimization is effected via intelligent idle mode current drain management. In an exemplary LTE cellular network context, the user equipment (UE) only powers on its transceiver for a subset of Discontinuous Reception (DRX) cycles based on e.g., the quality of the radio environment, power considerations, location, etc. For example, if a UE has not moved, and its radio reception quality is good, the UE is likely to successfully receive a paging notification (i.e., without multiple attempts). Consequently, the UE configures itself to receive only a single paging indication.

    Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. In prior art designs, the instantaneous jitter is derived from a weighted history of the media stream, and consequently only packets that have already arrived are used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.

    Abstract: A method and apparatus for fast cell selection by a mobile wireless device. The mobile wireless device detects when a first wireless cell fails a set of stored suitability criteria and searches for and locates a set of candidate wireless cells to associate with. The mobile wireless device measures at least one received signal metric for each candidate wireless cell in the set of candidate wireless cells. When a candidate cell in the set of candidate wireless cells is identically the first wireless cell, the mobile wireless device evaluates the suitability of the candidate wireless cell using the stored set of suitability criteria for the first wireless cell and the measured at least one received signal metric for the candidate wireless cell. The mobile wireless communication device associates with the candidate wireless cell when the candidate wireless cell meets the stored set of suitability criteria.

    Abstract: Methods and apparatus enabling a mobile device to receive paging notifications from multiple networks. In one embodiment of the present invention, a first device connected to a first network momentarily ignores the first network, to monitor a second network instead. The first device identifies and prioritizes a list of applications of the first network; the prioritized listing allows the first device to preempt one of its lower priority tasks to monitor the second network for paging messages instead. The described methods and apparatus enable e.g., GSM paging for Class B cellular devices which are connected to GPRS NMO-2 type networks. The Class B cellular device can ignore certain GPRS data (which is tolerant to error), to decode GSM paging channels, which would otherwise be missed.

    Abstract: Apparatus and methods for channel estimation in a Multimedia Broadcast Multicast Service (MBMS) Single Frequency Network (MBSFN) are disclosed. A representative method includes a wireless communication device receiving multiple frames, each frame including multiple subframes, each subframe including multiple symbols. The wireless communication device determines whether subframes include MBMS data or not. For subframes that include MBMS data, the wireless communication device excludes all or certain symbols of the subframes that include MBMS data from a channel estimation process. The wireless communication device determines whether the subframes include MBMS data based at least in part on a channel impulse response and/or a channel energy response for one or more symbols of the subframes.
